Wireless accelerometer project

[Jerome Demers] sent us his extremely detailed semester project. The two part system consists of PICs connected to XBee modules and accelerometers. By using the device a coach can monitor an athlete and correct their minute mistakes.

Did we mention [Jerome] was very detailed? He also goes into the particulars of designing the circuit, using solder paste and baking, designing and laser cutting a case, and even some fun stories. Well worth the read if you have the time.

LEGO hand controller


[David Hyman] built this device to control a LEGO claw. One one end of things is the part you wear, that measures movement of two fingers and your thumb. On the other end of things is a LEGO claw with three opposing digits. You move, it moves. The claw uses light sensors and a gradient strip for position feedback. There is also an up-down wrist action that uses a touch sensor as the input. This is impressive enough to give the sniper rifle a run for its money.

Massive MIDI station ditches the monitor

Who need’s a touch screen when you’ve got 800 inputs each backlit with an RGB LED? This impressive controller was built by Ander for use in his performances. He did it with the intent to get rid of the computer monitor in his setup. We think there’s something to be said about that. It seems weird to go to a performance and see the artist staring at a screen the whole time. Unfortunately we don’t have too many details about the hardware but we can tell you that he’s using Ableton Live on the software side of things.
